Drupal 7 Module Development is a book about writing modules for Drupal 7. It covers elements of Drupal including the theme system, entities, fields, install profiles, security, the database abstraction layer, JavaScript, and more. This was a book I co-wrote with Matt Butcher, Larry Garfield, John Albin Wilkins, Ken Rickard, and Greg Dunlap.

In the Mobile Drupal issue of the Drupal Watchdog magazine (Issue 2, Volume 1) I wrote an article titled "Big Performance Wins On The Front End". Front end performance (a.k.a. WPO) is one of my interests. In this article I look at the performance picture when it comes to websites and touch on some low barrier to entry tips websites can implement.
